Hello,
I want to convert node's name to uppercase with On Name Changed event.
So I tried this code
node = kwargs["node"]
name = node.name()
node.setName(name.upper(), True)
But if I try to rename the node, I get error
Unknown error when generating backtrace.
And the name is converted to uppercase but from node abc becomes node ABC498
Not sure where this 498 number and error come from.
I guess I am doing some beginner mistake.
Thanks,
Juraj

Hello guys,
I'm having a problem with my project. I have a destruction made in Houdini that I want to export to Maya. This is because it needs to be rendered in Maya. I am using an apprentice version of Houdini, because of this version a lot of export methods can't be used. The best chance I have is with OBJ sequence in my opinion. But when I write an OBJ sequence in Houdini and then export it (as a single file with file>import for testing purpose) to Maya it gives me the following error:
/ Error: line 0: OBJ file line 236743: index out of range for face creation. //
I am using packed geo most of the time. If I unpack the geo and then export it, it still isn't working. Attached is the OBJ that gives this error. I wrote it with a file node. The file node is attached to the Dopimport node with "fetch geometry from DOPnetwork" chosen as an option. Also tried polydoctor but it gives me no errors.
Can someone help me out?
Thanks in advance!

Hello, I think I've just blown my head trying to figure out a solution for this but I hope you can help me
I made a simulation of water and whitewater in Houdini and then used alembic to send the mesh to Maya for rendering. The whitewater particles were sent via the Realflow connectivity plugin in .bin format.
Maya had no problem opening both the water mesh and the whitewater particles, but my problem is that Maya can't compute any motion blur, I think this is because the files I exported do not have any motion vector information in them.
Is there any way I can export this information and use it in Maya?
To export the water mesh, I created the simulation and then I exported it to .bgeo sequence from the import node, then I re imported the .bgeo sequence in a new geometry file and created the mesh using the "particle fluid surface node" and from there I connected a ROP alembic output node.
To export the white water I got into the whitewater source node and in that level I created the RF Particle Export node and in it's properties I referenced whitewatersource.cache in the SOP Path
Also, I saw a video where v-ray proxy import is used to generate motion blur with some realflow mesh with the same problem, I don't know if I can do the same in Arnold, which is what I'm using for rendering. I'm quite new to the software but I'm loving it, if you can help me I'll appreciate it.
Thanks.
